Archaic Time Measures Calculator

The Sexagesimal Time System:

Medieval timekeepers used a base-60 system to divide time beyond seconds. Each unit is 1/60 of the previous unit, continuing the pattern of minutes and seconds.

About Archaic Time Measures

In medieval times, scholars continued the sexagesimal (base-60) system beyond minutes and seconds:

  • Minutes (prima) - "first" division of the hour (60 seconds)
  • Seconds (secunda) - "second" division of the hour (1 second)
  • Thirds (tertia) - "third" division (1/60 second)
  • Fourths (quarta) - "fourth" division (1/3600 second)
  • Fifths (quinta) - "fifth" division (1/216,000 second)
  • Sixths (sexta) - "sixth" division (1/12,960,000 second)

This system was inherited from ancient Babylonian mathematics and astronomy, which used base-60 counting. While these tiny divisions weren't practically measurable in medieval times, they were used in astronomical calculations and theoretical timekeeping.
